CAiR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 495,580, dated April18, 1893.

Application filed July 6,1892. Serial No. 439,190. (No model.)

To all whom it may concern:

Be it known that I, JOHN EGGNER CATTER- SON, a citizen of the UnitedStates, residing at Dayton, in the county of Oolumbia and State ofWashington, have invented a new and useful Oar-Coupler; and I do herebydeclare that the following is a full, clear, and eXactdescription.

This invention relates to certain new and useful improvements in carcouplings and it has for its objects among others to provide an improvedcoupler which shall be automatic iu its coupling action, which shall besimple in its construction, durable and eliicient in operation.

Other objects and advantages of the invention will hereinafter appearand the novel features thereof will be specifically defined by theappended claims.

The invention in the present instance resides in the peculiarcombinations, and the construction, arrangement and adaptation of parts,all as more fully hereinafter described, shown in the drawings and thenparticularly pointed out in the claims.

The invention is clearly illustrated in the accompanying drawings,which,with the numerals of reference marked thereon, form a part of thisspecification, and in which- Figure l is a side elevation of myimprovement applied to two cars a portion of which is shown and thecouplings engaged. Fig. 2 is a central vertical longitudinal sectionthrough two couplers connected together. Fig. 3 is an end elevation of acar showing the chains for uncoupling. Fig. 4 is a view of a pln.

Like numerals of reference indicate like parts throughout the severalviews in which they appear.

Referring now to the details of the drawings by numerals, l designatesthe drawhead provided with a recessed mouth as usual, and 2 is thecoupling link which is provided near each end with a slot or verticalrecess 2X in which are pivoted the gravity dogs '3 each of which issupported and pivoted upon the pin l which is arranged in thelongitudinal slot 3X of the link so as to have limited play bodily inthe slot of the link. The drawheads are provided with theverticalpassages as seen in Fig. 2 so that an ordinary coupling pin 8,seen in Fig. 4, can be used at either or both couplin gs when desired.The dogs 3 have inclined upper outer faces as seenin Fig. 2 and when intheir vertical positions they are adapted to be held against furthermovement by the shoulders 4 within the mouth of the drawhead as seen inFig. 2.

4 are levers pivoted on the pivots l0 held in the walls of the drawheadand having inclined outer ends to engage a corresponding wall inthedrawhead, as seen in Fig. 2. These levers work in chambers orrecesses in the pieces 5 secured transversely across the under side ofthe drawheads and in which are journaled shafts carrying the rollers 6over which the hoisting ropes or chains pass. These chains or ropes 9are attached to the under side of the levers 4 and pass downward throughsuitable holes in the pieces 5, over the rollers and thence up throughsuitable guides to the top of the car as seen in Figs. 1 and 3 wherethey may be provided with suitable handles as seen in Fig. 3, passingover rollers as 1l where necessary to diminish friction.

7 are the rods at the rear ends of the drawheads and around which arearranged the springs 7X acting in the usual manner.

The operation will be readily understood from the foregoing descriptionwhen taken in connection with the annexed drawings. Supposing a carprovided with my improvement and having the link held therein comeagainst another car provided with one of my improved drawheads; the endof the link enters the mouth of the drawhead and in so doing the gravitydog 3 will be forced into its slot in the link until the said dogreaches the opening 12 in the under side of the drawhead, which is anextension of the recess in which Works the lever 4 when the gravity dogwill assume a vertical position by its own Weight and held t IOO Thedevice is automatic and positive in its action and is not liable tobecome injured in the ordinary uses to Which it should be put.

What I claim as new is- 1. A coupling link for our couplings having arecess near each end and a gravity dog arranged in each recess andhaving its pivot Working in a longitudinal slot in the link, its setforth.

2. The combination with the drawhcad and the lever pivoted at the underside thereof and working in a recess in the under side of the drawhead,and a coupling link provided with a gravity dog adapted to engage behindthe lever, as set forth.

3. The combination with the drawhead and the lever pivoted on the underside thereof, of the coupling link provided With gravity dog, and achain connected to the lever, as set forth.

4. The combination with the drawhead provided with month and slot, uponits under side, of the lever pivoted to Work in said slot, a couplinglink provided with a gravity dog pivoted in :t recess in the link andhaving its pivot arranged to Work in a longitudinal slot in the link andhaving inclined face, and a. chain connected with the lever,substantially as and for the purpose specified.
